Definitions

  • This invention relates to a process for the partial combustion of solid fuel in particulate form and to a burner for carrying out such a process.
  • the burner according to this German patent document is provided with a valve member by which the fuel stream is diverted.
  • Such a burner is not suitable for high-pressure partial combustion since owing to a high density of the fue! stream a diversion of the fuel stream is difficult to accomplish. Premature combustion within the bumer would take place, especially if substantially pure oxygen would be used as oxygen-containing gas.
  • the present invention provides a process and burner for high-pressure partial combustion of solid fuel in which good mixing and a stable flame are attained and any premature combustion within the burner does not occur.
  • the invention therefore relates to a process for the combustion of a fuel in particulate form, in which process the fuel is centrally injected in a stream into a premix zone in which it encounters a primary supply of oxygen-containing gas which impinges on it, and in which process the fuel encounters a secondary supply of oxygen-containing gas, the mixture of fuel and oxygen-containing gas leaving the premix zone through a converging-diverging nozzle in order to enter the combustion zone, characterized in that the combustion is a high pressure combustion, that the primary supply of oxygen or oxygen-containing gas impinges on the fuel via a plurality of streams at an angle f3 of between 30 and 60° and at a velocity in excess of that of the fuel so that the streams penetrate the fuel stream, and that the secondary supply of oxygen or oxygen-containing gas is intro- ' quizd into the premix zone in the vicinity of the primary supply and at a velocity in excess of that of the fuel, so that it substantially forms a shroud of gas around the fuel leaving the nozzle.
  • the converging-diverging nozzle is also designed to provide an effective screen against radiation in order to supplement that provided by the dense cloud of particles leaving the nozzle.
  • the (relative) means velocity of the gas is between 10 and 70 m/s greater than that of the fuel.
  • the primary oxygen or oxygen-containing. gas is suitably injected at the centre of the fuel stream and it advantageously has a mean axial velocity when entering the premix zone of between 1.5 and 15 times that of the fuel particles.
  • the secondary oxygen or oxygen-containing gas is suitably injected at the circumference of the fuel stream and it advantageously has a mean axial velocity when entering the premix zone, of between 1.5 and 10 times that of the fuel particles.
  • the mean velocity of the stream of fuel and gas through the nozzle is between 35 and 100 m/s.
  • the outer shroud of gas comes into contact with hot combustion products which also contain some unbumed matter or gases.
  • the latter burn with the gas shroud which as a result tends to turn inwardly into the cloud of particles.
  • the velocity of the gas shroud being greater than that of the particles, it causes the latter to heat up very rapidly.
  • the resulting volatile components which are thus given off then enable combustion of the solid fuel to begin. Once started, the combustion is rapid and self-propagating due to the ready availability of oxygen or oxygen-containing gas at the centre of the particle stream. The flame is thus short and the combustion efficient and stable.
  • swirl number in this specification is defined as the non-dimensional quotient of the axial flux of the tangential momentum divided by the product of the axial flux of the axial momentum times the radius at the exit of the burner, taken at the exit of the burner).
  • the swirl number is preferably between 0 and 1.1.
  • the invention also relates to a burner for the partial combustion of fuel in particulate form which comprises a premix chamber having primary and secondary gas inlets situated around a fuel inlet port which is disposed in the same axis as an outlet in the form of a converging-diverging nozzle, characterized in that the primary gas inlets are directed radially inwardly at an angle of between 30 and 60° to the axis, the secondary inlet or inlets are arranged so that in operation they cause a uniform shroud of gas to be formed around the fuel leaving the nozzle, and a diverging section of the converging-diverging nozzle has an axial length of at least 0.5D where D is the diameter of the throat of the nozzle.
  • the secondary inlet or inlets is/are preferably situated outside the primary inlets and are at an angle of between 0 and 30° to the axis.
  • the secondary inlet comprises an annular slit, or series of slits forming an annulus, in the wall of the premix chamber.
  • the disposition of the secondary inlet(s) may equally be arranged to impart a rotation of the secondary supply of gas, for example by forming them at a skew to the axis in the case of individual ports, or by fitting swirl vanes in the annular slit or slits, according to the construction of the burner.
  • the wall of the premix chamber diverges outwardly from the fuel inlet, and the gas inlets are formed in it.
  • the wall may conveniently be at an angle of from 30 to 60° with respect to the axis (though in the opposite sense to that of the inclination of the primary inlets).
  • the said wall is conical, but it may also be in the form of any concave or convex surface of revolution, or polygon, either continuous or stepped, according to normal design considerations for flame stabilisation.
  • the diverging section of the nozzle will normally form the mouth of the burner and it may be between 30 and 60° to the axis.
  • the length L of the mouth is also important in preventing premature mixing with hot reactor gases and promoting turbulence in the fuel-gas mixture. Its maximum length will suitably be 3D.
  • a minimum length of L of at least 0.5D is necessary to obtain the necessary turbulence near the exit of the burner and to protect the premix chamber from excessive heat transfer from the flame and reactor gases.
  • the mouth may also be formed in such a way as to induce a higher swirl.
  • One particularly suitable form is in the shape of a tulip with a sharp angle between the throat and the beginning of the mouth and a smooth transition to a. substantially conical exit.
  • the transition may have a radius of from 0.25D to 0.6D and may be between 70° and 120°.
  • the length of the chamber measured from the fuel inlet to the start of the mouth should not be more than 3D. Its minimum length is governed by the physical constraint in providing the space for good fuel distribution in the premix chamber and in practice it will not be less than about 1 D.
  • the various inlet velocities and pressure should be controlled so that the swirl number is between 0 and 1.1. This will generally imply an optimum average stream velocity at this point of 70 m/s though the necessary conditions may well be met at velocities over the range 35 to 100 m/s in a typical burner.
  • the fuel will be delivered to the burner using a transport gas which is inert to the fuel particles.
  • This may be either recycled reactor gas, CO 2 , nitrogen or steam, or a mixture of two or three of the said gases.
  • the burner 10 comprises a premix chamber 12 having primary 14 and secondary 16 combustion gas inlets situated around a fuel inlet port 18.
  • An outlet 20 from the premix chamber is provided on the opposite side of the premix chamber from the fuel inlet port and is disposed co-axially with it.
  • the outlet is in the form of a converging-diverging nozzle having a converging section 22 and a diverging section 24 separated by throat 26 of diameter D.
  • the diverging section 24 of the nozzle which is the mouth of the burner has the function of controlling the expansion of the gases and solids as they leave the burner and enter the reaction chamber (not shown in detail, but situated at 28). Its half-angle should be between 30 and 60° to the axis 30 of the burner depending upon the exit velocity and scale of the burner.
  • the mouth shown in the upper part of the drawing has an angle a of 45°
  • the mouth 24 1 shown in the lower part of- the drawing is tulip-shaped and makes an angle ⁇ with the throat of the burner. It then has a smooth transition of radius R to a conical portion of half-angle a'. In the burner drawn 0 is 95° and R is 0.5D; a' is 45° as in the straight mouth 24.
  • the nose 36 of the bumer which contains the mouth 24 is subjected to a considerable heat flux and needs to be cooled.
  • the coolant flow is indicated by arrows 32, 34.
  • the inlets are connected with a gas supply, preferably of oxygen or an oxygen/steam mixture, via an annular duct 38.
  • the primary gas inlets are inclined at 45° to the axis 30 as is indicated by the angle f3.
  • the purpose of these inlets is to break up the stream of fuel particles emerging from the fuel port 18.
  • the velocity of the gas must be such as to penetrate the stream but not to reemerge on the opposite side of it. It is important that it remains within the particle stream, though still moving at a higher velocity.
  • the secondary gas inlets 16 are inclined at approximately 17° to the axis 30 (the angle is indicated by y in the drawing).
  • the angle y and the disposition of the inlets 16, of which there are 8 is important.
  • they are situated further from the fuel port 18 than the primary inlets 14 and are arranged so that in operation they substantially provide a shroud of gas around the fuel particles in the nozzle throat 26.
  • the shroud not only performs the initiation of the combustion of the particles but also reduces the mechanical abrasion on the nozzle throat 26.
  • the secondary inlets converge on the axis 30, i.e. the axis of each secondary gas inlet (16) and the axis (30) are situated in one plane.
  • the premix chamber 12 is considered to extend from the fuel inlet port 18 to the end of the throat 26, indicated by reference 40. Its length, indicated by M, should be between 1 and 3D in order to provide sufficient mixing time whilst not being so long that the fuel particles can be accelerated by the faster moving gas to such a point that the all important slip between the two phases is lost, nor the fuel from becoming so hot that the volatile components begin to be released, which could result in premature combustion. In the burner shown M is approximately 1.4D.
  • the burner is designed for ground coal whose dimensions are consistant with normal power station milling, e.g. Sauter mean diameter of approximately 50 to 75 micron.
  • the coal particles will normally be injected in combination with a small quantity of transport gas which may be steam, CO 2 , nitrogen or reactor gas for the production of hydrogen or CO/H 2 mixtures by partial oxidation.
  • transport gas which may be steam, CO 2 , nitrogen or reactor gas for the production of hydrogen or CO/H 2 mixtures by partial oxidation.
  • the burner is designed for a mean outlet velocity of 70 m/s at full load. This permits the burner to operate at a turn-down ratio of 2 at 35 m/s. Slight overload may be obtained by increasing the velocity up to 100 m/s. As shown the burner is designed to operate at a reactor pressure typically of 10 to 60 bar.
